• a genetically modified frog with translucent skin• red and black CG rocks• greasy red and black CG rocks in a tiling pattern• CG "lava" that looks like blobs of grease floating in oil• a translucent blue jellyfish with fuzzy orange organs in its middle• a translucent pink creature with some sort of chunky brown internal tract• fake-looking CG landscape with red soil, metallic reflective water, and a giant orange "sun" that doesn't light up the sky or cast light on the surface• blocks of white soap with embedded colorful translucent blocky bits in it• orange sea anemones with translucent tentacles

...all the non-CG images have translucency in common, while the CG images don't seem to have much in common except glowing red and orange colors. None of this looks particularly eye-catching, it's all different kinds of ugly.

Is there some "organic vs artificial" theme going on here? I'd really like to read the explanation.
